Volvo 15194903 Caliper Piston
The Volvo 15194903 caliper piston and Volvo 17218539 caliper piston are braking system components designed to transfer hydraulic pressure within the brake caliper assembly in Volvo equipment.
Caliper pistons are critical components within hydraulic braking systems. Their primary function is to convert hydraulic pressure into mechanical force, pressing brake pads against the disc to generate controlled stopping power.
The Volvo caliper piston is engineered to operate within demanding braking conditions where repeated pressure cycles and temperature variation occur. Proper piston movement ensures even brake pad contact and consistent braking response during operation.
The Volvo caliper piston 17218539 serves the same application and is used interchangeably depending on parts documentation and system configuration. Both references are designed to maintain sealing integrity and smooth piston travel within the caliper housing.
When caliper pistons become worn, corroded or damaged, braking performance may be affected. Symptoms can include uneven braking force, reduced stopping efficiency or abnormal wear on brake pads. Replacing worn piston components helps restore proper hydraulic pressure transfer and consistent braking behavior.
Regular inspection of braking components is recommended as part of routine maintenance. Installing the correct Volvo caliper piston reference helps maintain braking reliability, improve safety and extend the service life of the overall brake system.
